Application filed July 15,1925. Serial No. 43,723. g

I My invention relates to a door holder for holding a door in open position.

It is the principal object of the invention toprovide a simplified and cheap form of door holder. It is a further object to provide a door holder which may be used on either a right or left hand opening door, and which may be readily and simply adjusted for holding 0 the door in various positions of adjustment. Briefly stated, in the preferred form of the invention I employ two arms, to be secured to a door and a with or without the interposition of a door 5 closer such as is now commonly used. The arms are pivoted together at the ends and a spring urges the arms toward each other longitudinally of the pivot means. One or more detents are provided on one arm and extend longitudinally of the pivot means toward the other arm. The other arm has one or more detents complementary to the detents on the opposite arm, and a dc tent 011 one or the other of the arms is adjustable circumferentiallyso asto permit the arms to be held thereby in any desired position.

In the drawings which show, for illustrative purposes only a preferred form of the invention- Fig. 1 is a view of. a door holder applied and embodying features of the invention;

Fig. 2 is a side View in partial section of the door holder shown in Fig. 1';

Fig. 3 is a bottom plan view of the holder shown in Fig. 2; g

Fig. 4 is an end view of the holder shown Fig. 5 shows a plan and edge view of a detail. I

In said drawings 67 indicate arms, which are secured to a door casing 8 and a door 9, one arm 7, in the form shown, being connected to the door through the medium of a door closer 10. The arms 6--7 are pivot-ally connected together, as by means of a pin or bolt 11. A nut 12, threaded on one end of the bolt, serves to hold the arm 7 in place while the opposite end of the bolt, 11 passes into a oounterbore 13 in the arm 6 and is provided with a head 14 slidable in the oounterbore 13 and serving as an abutment for a coil spring 15, which bears thereon at one end and on the bottom of the 18, which are secured to the arm 6.

door casing, either oounterbore or a washer 16 therein. The

I spring 15, therefore, serves to-draw the two arms toward each other in a direction longitudinally of the connecting bolt 11', for a' purpose to be later describe a One of the arms, for example, the .arm

6, is provided with one or more detents 17 which, in the form shown, have substantially flat sides formed on the upper ends of 1 The other arm 7 has one or more detents complementary to the detents 17 on the arm 7 6 and, in. the form shown, these detents 19- 19' are formed by struck up portions on a sheet meta-l plate or disk 20. The disk 20 and the arm 7 are preferably non-rotatably held together, and in the illustration I have indicated number of teeth or serrations 21--21 on the arm 7 and have shown corresponding't'eeth 22 on the disk 20. In the preferred form the disk 20 is non-'rotatably held on theb'olt 11, as by means of an angular bore 23 therethrough fitting on a correspondingly shaped portion 24 on thebolt. I/Vhen the nut 12 is screwed up, and-the teeth 2122 in engagement with each other,

the disk 20 will be caused to move with the I arm 7. It is desirable to have the bolt 11 move'with'thefiarm 7,so that there will be no tendency for thenut 12 to become unscrewed when the device is in' use. I Obviously, by securing the disk '20 non-rotatablj on the bolt 11 and holding the disk pins 20 non-rotatably to the. arm 7 by means of the teeth or serrations, the bolt 11 will be caused to move with the arm 7 and "there will'be no te-nden'cyto unscrew the nut 12. The operation of the device is as follows: 'VVith the parts shown in Fig. 1,- the nut 12may be backed oif slightly so as topermit the teeth .2122

applied, for example, as

to become disengaged from each other, after which the disk 20, carrying the detents or holder lugs 19, may be relatively rotated to the desired position. The nut 12 may then be drawn up tight, so as to hold the disk 20, and consequently the lugs or detents19-19, non-rotatably on the arm 7 Now, when the door is opened-until the detents 17 engage the tapering sides of the complementary detents 19, the two detentswill other and causethe two arms to be separated longitudinally of the pivot means, this separation being permitted by the resilient conride up on each nection in the counterbored portion 13 of the arm 6. As soon as the detents have ridden past each other the spring 15 again urges the two arms together, and the latter will be held in such adjusted position.

Obviously, by backing oli on the nut 12 so as to permit the detents or lugs 19-19 to be positioned in various circumferential positions, the range of adjustment is very large, and the door may be held in substantially any position within the limits of adjustment of the device.

Since the arms will swing past each other, it will be clear from Figs. 2 and 3 that it is possible to use this door holder on either a right or a left hand opening door, Without making any changes other than adjusting the detents so as to hold the door in the desired position, and without turning the device upside down, as is required with some other holders now on the market, when it is desired to change from a left to a right hand opening door.

A door holder such as has been disclosed, is simple and relatively cheap to manufacture; will hold a door with the requisite degree of security, and will not be likely to get out of order.

While I have disclosed one preferred form of the invention I do not Wish to be strictly limited to the form shown, since obviously changes may be made within the scope of the invention as defined in the appended claims.

I claim:

1. In a door holder, a pair of arms, pivotal means for connecting said arms the connected ends of said arms being movable from and toward each other to a limited extent in a direction longitudinally of said pivotal means, a spring for urging said arms toward each other longitudinally of said pivotal means, and stop means movable with said arms and interposed in a space between said arms for holding the same in predetermined position of angular adjustment.

2. In the combination defined in claim 1, said stop means serving to move said arms apart in a direction longitudinally of said pivotal means, and said spring serving to move said arms toward each other in a direction longitudinally of said pivotal means when said stop means are in engagement with each other for holding said arms in said predetermined position.

3. In a door holder, a pair of arms, a pivot connecting said arms, means for permitting a limited relative movement between said arms longitudinally of said pivot, a spring for urging said arms toward each other, a plate separating said arms and adjustable on one of said arms circum'lierentially oi: said pivot, and abutment means carried by the first mentioned arm for cooperation with said other abutment, said spring permitting said arms to separate and to force the arms toward each other when the abutments there on are in engagement for holding said arms in predetermined position of angular adjustment.

4. In a door holder, a pair of arms, a pivot pin for pivotally connecting said arms, a sheet metal plate between said arms, and non-rotatable on said pin, cooperating teeth on said plate and one arm for holding said plate in various positions of adjustment on said arm circumferentially of said pivot pin, an abutment shoulder on said sheet metal plate, and another abutment shoulder on said other arm cooperating with said first mentioned abutment for holding said arms in predetermined position of angular adjustment.

5. In a door holder, an arm having an aperture therethrough and a counterbored portion, a second arm having an aperture therethrough, a pivot pin extending through said apertures for pivotally connecting said arms, a spring in said counterbored portion and engaging said pin for urging said arms toward each other, an abutment plate nonrotatably arranged on said pin and between said arms, one arm and said plate having cooperating teeth means for securing the same together in various positions of circumferential adjustment, abutment means on said plate, and coacting abutment means on said other arm, whereby when said arms are spread angularly, said abutments ride over each other against the tension of said spring and hold the arms in predetermined position.
